Abstract
A security object has a substrate () carrying a first motif () and mutually aligned thereto a second motif (). The first motif () is formed by a volume hologram () and visible under a given viewing condition only. The second motif () can e.g. be a dye, a surface hologram, a perforation or any other non-variable or optically variable device. The first and the second motif () combine to form a third motif, e.g. a legible text. The combination of the first motif () formed by a volume hologram () with the second motif provides an increased level of security.
